Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584610, here are decompositions:

3 + 31584607 = 31584610
59 + 31584551 = 31584610
179 + 31584431 = 31584610
227 + 31584383 = 31584610
311 + 31584299 = 31584610
347 + 31584263 = 31584610
419 + 31584191 = 31584610
467 + 31584143 = 31584610

Showing the first eight; more decompositions exist.
